FROM MTV.COM:Jim Carrey does not often go unnoticed. But when the actor showed up at the 1999 MTV Movie Awards, almost no one knew who he was. And the explanation for this odd turn of events constitutes one of the best and funniest moments in MTV Movie Awards history.

Carrey had been nominated for Best Male Performance for his turn in "The Truman Show" and decided to show up at the June '99 ceremony dressed as a straggly haired, chain-smoking hippie. From roles in "The Mask" to "How the Grinch Stole Christmas," Carrey is no stranger to disguises — only this time, he didn't tell anyone about his plan.
